Abstract
A vector data selection unit selects, from a vector file of a past line graph, each vector data of a time period where a new line graph overlaps. An attribute value setting unit sets, of the vector data selected, a high transparency degree value to oldest vector data, sets a low transparency degree value to newest vector data, and sets an intermediate transparency degree value to intermediate vector data. A graph display unit displays a portion of a time period of the past line graph where the new line graph overlaps, with a gradation.
Claims10
A graph generation apparatus comprising:
- a processor to execute a program;
- and
- a memory to store the program, past graph point group data, and new graph point group data, wherein
- the past graph point group data represents, in chronological order, a plurality of graph points included in a past line graph,
- the new graph point group data represents, in chronological order, a plurality of graph points included in a new line graph, and
- the program which, when executed by the processor, results in performance of steps comprising,
- selecting, as overlapping-portion data, graph point group data which represents a plurality of graph points included in an overlapping-portion graph, the overlapping-portion graph being a line graph of a time period of the past line graph where the new line graph overlaps, from the past graph point group data, and
- generating graph image data that represents, as the overlapping-portion graph, a line graph in which a display style of the overlapping-portion data gradually changes along a time axis.
A graph display apparatus comprising:
- a processor to execute a program;
- and
- a memory to store the program which, when executed by the processor, results in performance of steps comprising,
- displaying, based on past graph point group data representing, in chronological order, a plurality of graph points included in a past line graph, and new graph point group data representing, in chronological order, a plurality of graph points included in a new line graph, as an overlapping-portion graph, a line graph in which a display style of graph point group data gradually changes along a time axis, the graph point group data representing a plurality of graph points included in the overlapping-portion graph being a line graph of a time period of the past line graph where the new line graph overlaps.
A non-transitory computer readable medium having stored thereon past graph point group data, new graph point group data, and a graph generation program that when executed by a processor causes the processor to use the past graph point group data and the new graph point group data to perform
- an overlapping-portion data selection process to select, as overlapping-portion data, graph point group data which represents a plurality of graph points included in an overlapping-portion graph, the overlapping-portion graph being a line graph of a time period of the past line graph where the new line graph overlaps, from the past graph point group data;
- and
- a graph image data generation process to generate graph image data that represents, as the overlapping-portion graph, a line graph in which a display style of the overlapping-portion data gradually changes along a time axis, wherein
- the past graph point group data is data that represents, in chronological order, a plurality of graph points included in a past line graph, and
- the new graph point group data is data that represents, in chronological order, a plurality of graph points included in a new line graph.
A non-transitory computer readable medium having stored thereon a graph display program that when executed by a computer cause the computer to perform:
- a graph display process that displays, based on past graph point group data representing, in chronological order, a plurality of graph points included in a past line graph, and new graph point group data representing, in chronological order, a plurality of graph points included in a new line graph, as an overlapping-portion graph, a line graph in which a display style of graph point group data gradually changes along a time axis, the graph point group data representing a plurality of graph points included in the overlapping-portion graph being a line graph of a time period of the past line graph where the new line graph overlaps.
